In this paper, we model the human head using the Volume and Wang's constraint methods, and study the inhomogeneous anisotropic conductivity for white matter (WM) using finite element method (FEM). To represent the WM accurately, the conductivity ratio approximation (CRA) and statistical conductivity approximation (SCA) techniques are applied to assign inhomogeneous anisotropic conductivity. This model is evaluated and compared with a homogeneous isotropic model and a homogeneous anisotropic model. The results show that the effects of inhomogeneous anisotropic conductivity ofWM on the scalp EEG are significant.
在本文中，我们使用体积法和王的约束方法对人体头部进行建模，并使用有限元方法（FEM）研究白质（WM）的非均匀各向异性电导率。为了准确表示白质，应用电导率比近似（CRA）和统计电导率近似（SCA）技术来分配非均匀各向异性电导率。对该模型进行了评估，并与均匀各向同性模型和均匀各向异性模型进行了比较。结果表明，白质的非均匀各向异性电导率对头皮脑电图的影响是显著的。
